Extreme fan noise on Retina Macbook Pro "15 2012

My Macbook runs very loud without intensive apps open when I connect it to a Thunderbolt Display for over an hour. I have tested this to great length, it doesn't matter whether it's photoshop, microsoft word or google chrome that's running, it's the fact that it has to power an external display.
I have taken it to Apple Support, however they perform their cooling system tests in 18 degree airconditioning so it's impossible to demonstrate how loud it gets at normal room temperature.
I presented this problem twice within my warranty period, but Apple will simply do their test and deny any problem as the fans barely start up in the cold test environment. They did say that if my laptop overheats and becomes damaged, they will cover the damages because I made the complaint within the warranty period. Now my warranty has expried (I simply didn't have time to waste taking the computer to Apple again within the last two months).
Is there anything I can do to get my laptop fixed? I'm pretty sure the graphics card was faulty to begin with as it cannot take the load of a Thunderbolt Display over an extended period. There are so many documented cases of issues concerning fan noise and overheating with the 2012 rMBP, is Apple not going to do anything about it?!

High CPU usage will make the fans run faster (luder) you can try a SMC reset:

Follow directions for a battery that should not remove yourself. Also have the Apple tech make sure you do not have a bad temp sensor.

My non retina macbook pro mid 2012 will read the display its connected to but does not display anything at all

Hi there,
I have a macbook pro mid 2012 non retina display and i tried using an external display for it. I hooked it up and the screen blacked out and turned back on like normal and the computer itself was reading that the display was there. The only problem is that on the display itself there is no image of the macbook being displayed. im using a thunderbolt to vga connector and all the connection check out the only problem is the display. the display works on my other macbook that i have just fine i dont understand why it wouldnt work on this new one. Keep in mind i have had this computer for only 5 days.
Thanks in Advance

HELP! Retina Macbook Pro Late 2012 vs Late 2013

Hey guys, faced with a dilemma here and looking for some help
So, I am able to buy a Late 2012 retina MBP with the upgraded 2.9ghz i7, 8GB of RAM, and 500SSD. Seller is asking $1450, I think I can get it for $1400.
Now, the new Late 2013 retina Macbook Pro was just released as you all must know.
The Base model has a 2.4ghz i5 haswell chip, 4gb ram, and 128gb Pcie-based flash storage.
It retails for $1349 in Canada, and I think they have a student discount of $100, so with taxes in i'd be looking at around $1400 as well.
I think both computers will have more than enough power/space for my needs, although I want make sure I buy the best value/ will have the best resale value in the future.
What do you guys think? Is the Late 2013 rMBP upgrade a huge difference, and a must have in this situation?
Help would be appreciated
Thanks!

Thank you for your response! No actually, they are both the 13 inch models.
Specs wise though, do you think I will notice a difference between the two, if I am not using too heavy applications?
I will be majoring in Computer Science next year, so that's something im trying to keep in mind too.
I just read here in the discussion that the new retinas are having freezing issues as well. Hmm..
Might just hold off to make a decision..

Macbook Pro Mid 2012 15" Retina - Display blackout on restart.

I am having a major issue with my 15" Retina MacBook Pro (mid 2012). When I shutdown the Macbook, and boot it again later, it is not showing anything on screen.. Even the grey screen on bootup.. Completely black.. I can hear the startup chime, and a bit later, keyboard backlight turns on, which is indicating that the boot process is completed.. But no display.. Even for 15-20 min.. I cant even access Bootcamp and Apple Hardware test.. (Even if they are available, I can't see them on screen.. Fully black.. And I can't know where to click on what, in that darkness..)
But one small thing I found was, when the keyboard lights up, I just closed the lid.. It then goes to sleep.. Again opened it.. I found the screen working normal, after a small flashing of Blue screen.. I'm thinking that this problem occurs only at startup, but not at sleep.. This is not a solution, but a temporary remedy..
Can anybody help me over this issue..??

Hey SreeHarsha Vardhan,

Lag when system sounds play on Retina MacBook Pro

I have a problem on my Retina Macbook Pro (Mid 2012, running on 10.9 Mavericks) that has persisted for quite some time.
Essentially the problem is that whenever an application plays a system sound, the application lags for a few seconds. However, this comes and goes.
For an example of what I mean, the lag happens when I make the following actions:
- Deleting a file in Finder (Trash sound should play)
- Using a 'find' prompt in an app like Chrome, Xcode, TextEdit, and entering a string that cannot be found. That is, the lag occurs when I type the character that causes no result to be found. (Beep should play)
- Pressing 'delete' (backspace) in any app's text field with no text present (Beep should play)
- If I go to System Preferences -> Sound, and select a new 'alert sound' in the Sound Effects tab, the lag occurs and the Console prints "System Preferences[52828]: Error 268435460 setting AlertSound"
While my computer is in 'problem' mode, every single app is guaranteed to lag when these events happen.
But as I said, the problem comes and goes. It first happened after I had to reinstall one day. I think I screwed something up with preferences, permissions and such, because it took a while for me to fix everything up. But I don't think I quite fixed everything, because this problem started to occur ever since then.
The problem will appear for days or weeks at a time and then disappear for weeks. Just now I'm posting this thread because it had actually gone away for months, and just reappeared today. Nothing that I have found can explicitly start or stop this problem from occurring, it's seemingly random.
Does anybody have any idea why this would occur, and what can be done to fix it other than a complete clean reinstall?
Thanks!

Sorry wrong post to this thread.
Now the right post.
No OS X can not use all 8GBs of RAM when the Windows Virtual Machine is running. As long as the Win VM is up and running it take all the RAM you allocated to it. So if you allocated 2GBs of RAM to the VM OS X can only use the other 6GBs. As for the CPUs OS X can use all the cores and or Virtual core as all current Intel CPUs show as double the physical number of cores. So if you have a Dual Core i5 it will look like you have 4 cores. It's done with HyperThreading.

Retina Macbook pro audio quality is bad in windows 8.1

Like the title states, my Retina Macbook pro's (2012 model) audio quality is very bad in windows 8.1. It is unbearable to listen to music on it. I am using the latest bootcamp drivers, 5.1. I believe this is a driver problem, as it sounds fine in OS X. I tried to find the proper driver myself with no luck. I feel this is unacceptable on a computer I spent so much money on. Any help would be greatly appreciated.

Yes...
I also just recently purchased a MacBook Pro retina 15 (mid-2014) with bootcamp (windows 8.1) installed. While using my windows partition, the MBP seems to be running a bit hot, at least hotter than the OS X partition.
As for comparison, I have the 2012 MacBook Pro retina 13 with bootcamp (windows 8.1). It does not get as hot as the 15, and in fact, I don't think it runs hotter than OS X...
Any thoughts? Is it perhaps because I have the NVIVIDA dedicated graphics and in the windows partition, IRIS PRO isn't running?

Retina Macbook Pro strange fan noise

Hi all, i just got my retina macbook pro 2 days ago, however when starting it up for the first time there was a strange noise coming from the computer (probably fans), it was like a blocked fan kicking in loudly but only for a few seconds. I figured that it was nothing but it came back when i used it today and i noticed that this sound is only present when the computer is warm. It only comes for a few seconds and then fades away, is this normal? I'll try to post a recording up here if i can.

I have the same problem with my MacBook Pro Retina . . . took it into my local Genius Bar, where a nice woman identified it as noise from one (or both?) of the fans. She took it apart, removed some debris (couldn't have been much, after a couple of months) and . . . the computer continues to make this annoying noise.
I believe this must be a serious design flaw on Apple's part, and that they don't know what to do about it.
We can hope that the noise is merely annoying, and not a danger sign.

Heat and Fan on Retina MacBook Pro

Hi Guys,
This is my first post in the forums and I just wanted some advice on an issue. I know there are existing discussions - but I've read conflicting answers in each. I'd like to know if the fan and heat I'm experience on my brand new 15 inch mid-2014 Retina MacBook Pro is normal.
I use Adobe Premiere Pro CC to edit 1080p video for a YouTube channel. I've noticed that after I begin exporting the fans kick in within seconds and the heat jumps up substantially. Idle, the temperature I've measured with SMC fan control is roughly 35-40 degrees, but within a minute of exporting - this jumps up to around 98/99 degrees. I understand that the fans would start after a certain amount of time and that the temperature would rise. But is it normal to rise to 99 degrees????
I've not noticed this with games, but just when exporting.
Thanks for any help.

That screen shot is very helpful. You have a four core CPU and each core can handle two threads so the %CPU can be over 100%. In your case, it's over 700% total usage with 800% being all there is available, so your rMBP is working very hard indeed. While I start cranking up the fan speed using smcFanControl just as you are, there's just so much the fans can do given that load. And we don't know how hard the graphics coprocessor is working, and that just adds more heat. I suspect the lower temperature may be because the intake ports may have been partially blocked on your lap; it really doesn't take much given their location. It looks like your laptop is doing the best it can.
There's a reason why five large fans were used in the Mac Pro towers (not counting the graphics card fan).

Retina MacBook Pro fan very loud and usb mouse disconnecting when restarting the computer

2 days ago, I got a brand new retina MacBook Pro 13 inch with the specs 2.8 GhZ i7, 8 gigs of ram and 512gb ssd. It should definitely be functioning properly since it's a really expensive computer, but I already noticed a few problems that I hope you can help me with.
So first of all, when I play World of Warcraft, the fan seems to go up to 6000rpm and is very loud. I checked the activity monitor and it says WoW is using about 60% CPU, so it shouldn't have to be that loud. I also installed smcfancontrol, but it doesn't seem to lower the speed of the fan.
I ran an apple diagnostics test and it couldn't find any problems, and I also tried resetting my smc, but the fan is still going very loud.
And the second problem I have is, that when I have my mouse usb connected to my Mac, and I restart it, it can't detect the mouse anymore. So I'd have to pull out the usb plug and put it back in everytime I turn on my computer. isn't it supposed to automatically connect to my mouse when it's already plugged in?

Matt,

Retina MacBook Pro is not connecting with Airport Extreme 5 GHz signal

I believe I have done my due diligence to find the answer to my question here and other places but I must be missing it. I have a Retina MacBook Pro that as far as I know should select the 5 GHz signal from my Airport Extreme (Generation 1 with 7.6.4 firmware) which is literally 3 ft. from my computer. When I click on the Airport icon in the menu bar, it is indicating a 2.4 GHz connection. I have looked at discussions which say I can give separate names to to both the 2.4 GHz and 5 GHz signals. I can't seem to find that. I also read where you can reorder the order of signal preference. I can't seem to find that either. Interestingly, I have an Airport Express that is extending the network. When option clicking on its icon in airport utility, I can see both the 2.4 and 5 GHz information. I don't se that in the Airport Extreme. I am thinking about gettng the newest Airport Extreme but if I don't need to...
Thanks for any help!

as far as I know should select the 5 GHz signal from my Airport Extreme (Generation 1 with 7.6.4 firmware) which is literally 3 ft. from my computer
A Generation 1 AirPort Extreme is not a simultaneous dual band wireless router. It can produce either a 2.4 GHz....or....a 5 GHz wireless network signal, but not both simultaneously.
If you want the Gen 1 Extreme to produce and deliver a 5 GHz wireless network, it can do so, but any 2.4 GHz devices that you have will not be able to connect to the 5 GHz signal.
A new simultaneous dual band AirPort Extreme will produce both a 2.4 GHz and 5 GHz signal simultaneously. Wireless devices will automatically connect to the best signal quality based on their capabilities and location in relation to the AirPort Extreme.

My Retina Macbook Pro is making this weird noise

My recently purhcased 2.7 Retina Macbook Pro has made this noise a few times from awaking the computer from sleep. Does anyone know what it is?
http://www.sendspace.com/file/prlzhh

How do you turn them down or off? I don't even know how they turned on to begin with. They have never turned on before and I've had my Mac Pro for 3months. I just turn my Mac off it starts doing it again when I turn it back on

Late 2013 Retina Macbook Pro power brick extremely hot to the touch! This affected my computer (It was hot as well) - I could smell something burning! I am unsure the issue!

Hello,
I purchase the latest 2013 Retina Macbook Pro, which I pluged in my charger and walked away from my computer! When I arrived, my computer was in sleep mode and I noticed a faint burning smell and felt my computer and it was extremely HOT! I then felt the power brick and it was even hotter! 10 minutes after I awoke the computer (ESTIMATED), the computer actually cooled down... It's not hot to the touch but still warm! On the other hand, the power brick is still extremely HOT!
Please help! I started the charge at 3% and awoke it around 78% and now it's at 89%
Also, how long does it take to charge from 3% to 100%? It's been about 2 hours to reach 89%
Thanks,
Anthony
NOTE: Any support would be great! I could use the advice as this is personally my first MAC! I am thinking a software update to fix the computer from heating up when sleeping but I am unsure about the power brick!

I always thought that keeping it plugged in nearly 24/7 can damage the battery too?
No, not at all, the only damage from being plugged in all the time are IF:
A: its not turned off and in sleep mode ALL the time while plugged in
B: you dont unplug it ever couple weeks or so and drain the battery down to about 30 to 40%
*Also, if youre going to store your macbook away for a few weeks or more,... make sure it has at least a 50% or so charge.
*Cycle count / use/ lifespan is one thing that cant be countered.
Proper treatment is another thing. Just because LiPo batteries dont need conditioning in general,.. does NOT mean they dont have an ideal use / recharge environment. Anything can be abused even if it doesnt need conditioning.
Just use and enjoy your new macbook,
From Apple on batteries:
http://www.apple.com/batteries/notebooks.html
http://support.apple.com/kb/HT1446
but really all you would keep in mind is --"consider 15-20% is the same as 0% and recharge it"
Important useful info on your Lithium cells as compiled from battery experts:
Heat increases battery performance but shortens life by a factor of two for every 10°C increase above 25–30°C (18°F above 77–86°F). This is yet another important reason for the cooling of any notebook, not just keeping the processor and GPU cool. Mavericks lower power tasking (app nap) and combined with the cool running Haswell processor both greatly protect battery life on your Macbook now more than ever before.
Good news: *Mavericks not only increases a single charge cycle for longer battery use off a full charge,… but also prolongs the overall long term life of the LiPo battery in a Macbook by reducing the load conditions the battery experiences from heavy peak-use.
Counting cycles is not conclusive because a discharge may vary in depth and there are no clearly defined standards of what constitutes a charge cycle on a Lithium Ion battery empirically. Similar to a mechanical device that wears out faster with heavy use, so also does the depth of discharge (DoD) determine the cycle count.
The shorter the discharge (low DoD), the longer the battery will last. If at all possible, avoid full discharges and charge the battery more often between uses. Partial discharge on Li-ion is fine.
Frequent HIGH depth of discharge rates (draining the battery very low) on a Lithium battery will hasten the lowering of maximum battery capacity.
Although better performing when warm, lithium polymer batteries live longer when kept cool.
Lithium cells prefer draining conditions at a steady pace rather than fast pulsed or quick discharges, …this fact is idealized now with the Haswell and Mavericks app-nap low power tasking for battery use.

I am new to Apple (Retina MacBook Pro), how can I maximize my experience?

Hello, I recently joined the Apple world by purchasing a 13" Retina MacBook Pro. So far, I couldn't be happier. I changed platforms from Google because the devices I have don't allow for local content playback and apps are buggy and slow to respond. (I also hate Windows 8 with a passion). I want to get the most out of my Mac and the Apple ecosystem so I would like to get some feedback from other users about how best to accomplish the following:
Seamless media syncing and playback on TV, phone, and computer
Planning to get an iPhone 6 and upgrade to Yosemite so personal data, photos, music, and video is accounted for
I have used Google Chromecast and have Google Play's music client, but uploading content to that environment is another step
I already have a modem w/ wireless and router built in courtesy of my internet provider, what would be the benefit, if any, to getting an AirPort Express, Extreme, etc?Would like the ability to back up my data - external hard drive is adequate, but wireless backup is tempting
I do writing and programming and I am already getting familiar with iBooks, iUniversity, and XCode - any other suggestions?
I am happy to be a part of the Apple world! Now I want to see what it can do! The bottom line is I want seamless access to all of my content across the devices I have.

I have a MacBook. I purchased things apps like Pages, Numbers. etc in the App store. Im' just wondering how to put them on the new MacBook Pro without having to purchase them again. Will the Migration Assistant do this?

Looking for a Hard Case/Shell for my new Retina MacBook Pro 15"?

I am looking to buy a shell/case for my rMBP (October 2013) it hasn't arrived yet, but obviously I want it to be protected asap.
I don't know what the model number is, but it is the lower spec 15" Retina MacBook Pro that I have purchased. How can I make sure that a case I buy will fit?
Will any 15" rMBP case fit, or has the size changed for this upgrade?
I am looking for either a black/clear, shell/case that will attach to the back of the lid to protect it. I am looking on eBay at the moment, as I have a voucher to spend on there anyway. Can someone recommend a shop/seller or a particular product?
I am in the UK, so I would obviously prefer to buy from a local seller.
Thanks!

I purchased the Hardshell Case for 13-inch MacBook. It offers a durable hardcase construction that securely covers your notebook. It provides a frosted hardshell exterior, soft-touch coating, raised rubber feet, thermal vents, and trouble-free access to all features.
Features
Excellent notebook protection
Exterior rubberized soft-touch coating
Precise cut-outs for access to magnetic power cable, headphone and microphone input jacks, CD-ROM drive, battery level check button, and all side ports
Vents and rubber feet elevate notebook from surface, allowing notebook's internal fans to circulate air more freely
Simple to use and easy to clean
I really love it. My friend has dropped their macbook (the case was on) on the concrete and nothing happened to the computer.
Hope this helps you.

OSX 8.2 new Retina Macbook Pro won't wake from sleep.

Since upgrade to OSX 8.2 new Retina Macbook Pro won't wake from sleep. Tablet lights are on in morning and fans running like crazy, but it requires hard quit and start. Tried with no apps running, no change. It was fine before this last update. Wasn't the recent firmware update supposed to fix this issue? It seems to have started one for me.

I have the exact same problem with my Macbook Pro OS 10.8.4. What happens is: I work on the train, press cmd/alt + eject to put to sleep..pop it in my bag...get home or office... open the lid...and nothing! Battery indicator shows I have plenty of juice but it will not wake up no matter what key I press.
The only difference between use on the train and home/office is the plugging in of peripherals and mains power. It happens sparadicially, perhaps once or twice a week and I always send a 'panic report', so somewhere there will be approx 20 reports of this fault at Apple.
